Voices of North American Owls.
Cornell Lab of Ornithology, The Macaulay Library, 2006.
2 CDs. $29.95

Listen to a sample track:
Barred Owl (Strix varia) - Pair caterwauling. Recorded by Gerrit Vyn and Benjamin M. Clock.

On this 2-CD audio guide you'll hear nearly 200 tracks featuring the hoots, screams, chitters, squawks, squeals, bill claps and barks of 19 regularly occurring species and two rarities. That makes it the most comprehensive guide to owl vocalizations available.

Owls have a rich repertoire of sounds for communicating in the dark. A 56-page booklet with full-color images describes the wide variety of vocalizations made by each species. A brief text describes the vocal behavior of each species, with a color photo of the species on the page opposite. The many vocalizations are listed by track number, and described in detail. The booklet also includes an alphabetized list of species and vocalization types.

The recording quality, as with all Cornell Lab audio publications, is exceptional. The tracks are not announced. Total playing time is one hour, forty-five minutes.

This CD set will help birders identify these denizens of the night - from the ghostly Barn Owl, to the tiny Elf Owl, to the familiar Great Horned Owl. You'll gain a greater appreciation for owls and their sounds and behaviors.
